OTTO HOLZHUER, OF AUGSBURG, GERMANY.

MACHINE FOR STRETCI-IING- AND STRAIGHTENING WI-IALEBONE.

To all whom it may concern:

Be it known that I, OTTO HOLZI-IUER, engineer, a subject of the King of Bavaria and German Emperor, residing at Augsburg, in the Kingdom of Bavaria and Empire of Germany, have invented certain new and useful Improvements in Machines for Stretching and Straightening lVhalebone, of which the following is a specification.

The present invention relates to an adhesion ironing machine for whalebone in order to be able to stretch and straighten the same. This ironing machine changes the raw whalebone in one single operation into marketable strips of whalebone, and a smoothness and polish can be obtained without there being any appreciable waste.

As compared with Older devices for straightening and ironing strips of whalebonc, the present machine is ditferentiated by great simplicity and small amount of waste.

In order that the invention may be clearly understood, reference-is made to the accompanying drawing in which one embodiment is represented by way of example, and in which:-

Figure 1 is a side elevation of part of the nachine and a section through the ironing mechanism, whereas Fig. 2 is a front elevation partly in section, Fig. 3 a plan, and Fig. 4: an elevation with a section through the spring-pressed, grooved irons combined to form an endless chain.

Eeferring to the drawings, the strips of whalebone which are still raw and for the most part curved like a sword are placed at the feeding-bridge A. Supposing the machine to be five-partite, e. five strips can be inserted atonce, the first roller B seizes all five strips on the feeding-bridge A and conveys the same onto the horizontal grooved track or disk C which is heated to a certain temperature by blow-pipe flames for eX- ample. The heating of the disk C is indispensable, since whalebone can only be bent, stretched and ircnecl when heated. The whalebone must be so inserted that the natural curvature of the same is opposed to that of the horizontal disk C. The small rollers E are under the pressure of the Spral Springs Specification of Letters Patent.

G and are driven by bevel-wheels F. The whalebone being run by the rollers E between the roller D of the horizontal track or disk C, is bent in a manner contrary to its original State. The strips are then conveyed between the slightly warined endless chains H and K which are likewise grooved and engage in one another; these chains are driven at different speeds, the upper chain H running faster than the lower, whereby the whalebone obtains a polish and shape, so that it passes from the machine through chute I ready for use. The grooved chains H and K are pressed one against the other by the bolts N pivoted on the straight track L, these bolts N being provided with regulatable spiral springs G.

\That I claim as my invention and desire to secnre by Letters Patent is l. In an ironing nachine tor stretcling and straightening whalebone, the combination with a circular grooved track (C), spring-pressed grooved rollers mounted over and gearing with the track, and means for rotating said track, of two superposed endless chains (H, K) composed of irons, means pressing the latter together, means for driving said chains at different speeds, and roller (D) t'or guiding whalebone from said track to between said chains.

2. An ironing inachine for stretching and straightening whalebone, comprising in combination a grooved disk (C) having a rack, spring-pressed grcoved rollers running on said disk, toothed wheels on said rollers meshing with said rack, means for rotating said disk, two superposed grooved endless chains (H, K), spring-pressed means pressing the top of one chain against the bottom of the other chain, said chains being adapted to be driven at different speeds and consistin of a plurality of grooved irons adapted to be heated, and grooved roller (D) for guiding wnalebone from said disk to between said chains.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.
